Monoclonal Mouse Purified B IH
Tight junctions function to maintain cellular polarity and permeability barriers in epithelial and endothelial cells. Several molecules of the tight junction complex have been identified. The bartomin protein is preferentially localized at the periphery of tight junctions of hepatocytes and other epithelia. The antigen is also detectable in the intestine and kidney. Studies with Madin-Darby canine kidney (MDCK) cells indicate the antigen to be an important molecule for regulation of the barrier function of tight junctions. Confocal laser scanning microscopy revealed that the expression of the antigen decreased sequentially during hepatocarcinogenesis. The antigen was expressed intensely at the apical and basolateral membrane of cancer cells with glandular pattern. Examination of human gastric and colon cancer tissues showed that tight junctions were maintained highly in the well-differentiated (gland-forming) adenocarcinomas, but reduced in poorly-differentiated adenocarcinomas. In MDCK cells the disappearance of antigen expression is closely related with cell spreading in vitro induced hepatocyte growth factor/scatter factor.
